Monitoring of specific port without using NNM

[M. Ismail]

Hi *,

Is it possible to monitor specific port on HP-UX without using NNM(HP Openview).
Is there any simple tool to do this.

Regds,
Ismail.

Yes, there are many native unix tools available, few to mention

1. netstat
2. lsof
3. nmap

All these utilities can be used to check whether particular port is used or not.

You can write a small shell script around these utilities and can do monitor the port

Hope this helps
Vijay

Dear All,

Thanks a lot for your replies.

Dear Kapil,

Thanks a lot for your on dot answer to my query.

I have added '-r' to the lsof command to continously monitor the port.

"lsof -r -i tcp:"

Thanks and Regards,
Ismail.

If by monitor a port you mean see traffic to/from that port number, then you would want to use nettl or tcpdump or perhaps ethereal.
